Book Description
On one of North America's last remaining expanses of grassland the Nature Conservancy has begun what is perhaps the boldest ecological experiment ever attempted. They are not simply conserving the natural beauty of this place, where eight-foot-tall grasses roll for miles under limitless prairie skies; they are studying it and shaping it anew, bringing back the bison once hunted here by native Plains horsemen, and seeding with fire to liberate the natural biodiversity of a land never broken by the plow. On the stage that is the Tallgrass Prairie Preserve many dramas have unfolded. Indians, white settlers, ranchers, oil barons, scientists, and politicians have all taken roles alongside Nature's players - geologic phenomena, weather, the intricately interwoven lives of plants and animals. In Big Bluestem, Annick Smith traces the fascinating story of this land that, like the grasses, endures, and should endure, in its glory forever.

Book Description
The frontier images of America embrace endless horizons, majestic herds of native ungulates, and romanticized life-styles of nomadie peoples. The images were mere reflections of vertebrates living in harmony in an ecosystem driven by the unpre dictable local and regional effects of drought, frre, and grazing. Those effects, often referred to as ecological "disturbanees," are rather the driving forces on which species depended to create the spatial and temporal heterogeneity that favored ecological prerequisites for survival. Alandscape viewed by European descendants as monotony interrupted only by extremes in weather and commonly referred to as the "Great American Desert," this country was to be rushed through and cursed, a barrier that hindered access to the deep soils of the Oregon country, the rich minerals of California and Colorado, and the religious freedom sought in Utah. Those who stayed (for lack of resources or stamina) spent a century trying to moderate the ecological dynamics of Great Plains prairies by suppressing fires, planting trees and exotic grasses, poisoning rodents, diverting waters, and homogenizing the dynamies of grazing with endless fences-all creating bound an otherwise boundless vista. aries in Historically, travelers and settlers referred to the area of tallgrasses along the western edge of the deciduous forest and extending midway across Kansas as the "True Prairie. " The grasses thlnned and became shorter to the west, an area known then as the Great Plains.

Book Description
Bioenergy and biofuels are generated from a wide variety of feedstock. Fuels have been converted from a wide range of sources from vegetable oils to grains and sugarcane. Second generation biofuels are being developed around dedicated, non-food energy crops, such as switchgrass and Miscanthus, with an eye toward bioenergy sustainability. Bioenergy Feedstocks: Breeding and Genetics looks at advances in our understanding of the genetics and breeding practices across this diverse range of crops and provides readers with a valuable tool to improve cultivars and increase energy crop yields. Bioenergy Feedstocks: Breeding and Genetics opens with chapters focusing primarily on advances in the genetics and molecular biology of dedicated energy crops. These chapters provide in-depth coverage of new, high-potential feedstocks. The remaining chapters provide valuable overview of breeding efforts of current feedstocks with specific attention paid to the development of bioenergy traits. Coverage in these chapters includes crops such as sorghum, energy canes, corn, and other grasses and forages. The final chapters explore the role of transgenics in bioenergy feedstock production and the development of low-input strategies for producing bioenergy crops. A timely collection of work from a global team of bioenergy researchers and crop scientists, Bioenergy Feedstocks: Breeding and Genetics is an essential reference on cultivar improvement of biomass feedstock crops.

Book Description
This book studies the application of green roofs in ecoregions of the western United States and Canada. While green roofs were intended to sustain local or regional vegetation, this volume describes how green roofs in their modern form are typically planted with a low-diversity mix of sedums from Europe or Asia. The authors demonstrate how in the western USA and Canada many green roofs have been designed with native plants and have been found to thrive. Part I of this book covers theory and an overview of ecoregions and their implications for green roofs. In Part II vegetation from prairies, deserts, montane meadows, coastal meadows, and scrub and sub-alpine habitats are explored on seventy-three ecoregional green roofs. Case studies explore design concepts, materials, watering and maintenance, wildlife, plant species, and lessons learned. Part III covers an overview of ecoregional green roofs and a future outlook. This book is aimed at professionals, designers, researchers, students and educators with an interest in green roofs and the preservation of biodiversity.

Book Description
The Archaeology of Large-Scale Manipulation of Prey explores the social and functional aspects of large-scale hunting adaptations in the archaeological record. Mass-kill hunting strategies are ubiquitous in human prehistory and exhibit culturally specific economic, social, environmental, and demographic markers. Here, seven case studies—primarily from the Americas and spanning from the Folsom period on the Great Plains to the ethnographic present in Australia—expand the understanding of large-scale hunting methods beyond the customary role of subsistence and survival to include the social and political realms within which large-scale hunting adaptations evolved. Addressing a diverse assortment of archaeological issues relating to the archaeological signatures and interpretation of mass-kill sites, The Archaeology of Large-Scale Manipulation of Prey reevaluates and rephrases the deep-time development of hunting and the themes of subsistence to provide a foundation for the future study of hunting adaptations around the globe. Authors illustrate various perspectives and avenues of investigation, making this an important contribution to the field of zooarchaeology and the study of hunter-gatherer societies throughout history. The book will appeal to archaeologists, ethnologists, and ecologists alike. Contributors: Jane Balme, Jonathan Driver, Adam C. Graves, David Maxwell, Ulla Odgaard, John D. Speth, María Nieves Zedeño

Book Description
To frame his story, Schneiders goes back to the nineteenth-century journals of fur traders and settlers and in the record of flora, fauna, floods, and human activity he finds evidence of rapid and disruptive change. Bison once had the greatest influence on the land, and Schneiders depicts an original bison and Indian trail networks on which were overlaid the first torts and towns and then the railroads, highways, and reservoirs that reconfigured the region forever.
